From the foregoing, t e essential features, elements and the operationof the device, together with the simplicity'thereof, will be clearlyapparent.

Havin what is c aimed as new and useful is 1. In a dump car, a bottomtherefor comprising two hinged parts having links pivoted to their freeswing; portions, itmen connected to the lin and a U-s aped lever 'votedto the i'trngn, so as to raiseland pwer the hinged parts.

I 2. In a dump car, a bottom therefor comirising two hinged artsextending ap roximate y the length 0 the car, a U-shape lever com :isingarms or side pieces pivoted at each end of the car, and itmen and linksconnected between the iinged parts and the side pieces or arms.

3. In a dump car, a bottom therefor comprising two hinged parts, aU-shaped lever comprising arms or side pieces pivoted to the ends of thecar, and pitmen and links pivoted -between the said arms or side piecesand the free swinging ortions of the hinged parts and so dispose withrelation to the hinged I bottom and the side pieces of the lever as to'hold the hinged parts in a closed position when the U-shaped lever is'disposed in a horizontal (position.

4. In a ump car, abottom therefor comprising two hinged parts, a U-shaped lever comprising arms or side ieces having curved portionspivoted to eit er end of the car ineans'connected between the hingedparts 40 an the curved portions for raising and lowprin the parts whenthe lever is manipuate 5. In a dump car, a bottom therefor comprisingtwo hinged parts, a U-shaped lever comprising arms or side ieces havingcurved portions pivoted to sit er end of the car, pitmen and linksconnected between the curved portions and the free swinging. porthusfully described the invention, 1

tions of the hinged parts, said curved portions being so constructedthat the pivots between the pitmen and the curved portions and the saidlinks will be disposed in alinement with the pivots of the side ieces orarms when the U-shaped lever is t rown in a horizontal position.

6. In a dump car, a bottom therefor comprising two hinged parts, aU-shaped lever comprising a beam havin arms or side ieces connecteddetachabIy thereto and aving curved portions, said arms or side piecesbeing pivoted at either end of the car, pitmen connected to theextremities of said curved portions and links connected between thepitmen and the free swingin portions of the hinged parts, said curveportions being so constructed that the pivots between the pitmen and thecurved portions and the said links will be disposed in alinement Withthepivots of the side pieces or arms when the U-shaped lever is thrown in ahorizontal osition.

7. In a ump car, a bottom therefor comrising two movable parts adapted,when eing opened,- to swing outwardly toward either side' of the car anddownward,'a U- shaped lever comprising abeam having arms or side piecesconnected detachably thereto and having curved portions, said arms orside pieces being pivoted at either end of the car, itmen connected tothe extremities of sai curved ortions and links connected between thepitmen and the free swinging portions of the hinged parts, said curvedportions being so constructed that the pivots between the pitmen and thecurved ortions and the said links will be disposed in alinement with thepivots of the side pieces or arms when the U-shaped lever is thrown in ahorizontal osition.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
